Toner cartridges are a main concern for laser printers and contribute to the overall cost of a budget in printing more so than other consumables. Almost every manufacturer, original and 3rd party alike, offer high yield toners and businesses want to know if they truly are high yield. The answer is yes. Through development manufacturers have enabled more efficient uses of toners and the systems by which they are applied to the page. Toner particles can now be made to extremely precise sizes and measurements. The chemical production of these toner particles makes them smaller and in turn easier to place more accurately on the printed page.

Toner particles are encased in a wax like material that keeps them from adhering to each other during the printing process. This substance has been redesigned for s a few improvements in the application process. First, the wax substance now has a lower melting point which means that the toner particles are released and applied to the page quicker. This reduces the amount of fluctuations that can occur if a toner particle does not reach the proper melting temperature; this causes more toner to be used than is necessary.

It may seem that smaller toner particles would mean a higher ratio of particles on the page, but when coupled with advanced electrostatic technologies they are used in a much more efficient manner. By improving the electrostatic process a single toner particle can be placed more accurately to the page. Laser printers use a difference in electrical charges to place toner particles to a page, and by being able to control the electrostatic field more closely the particles can be placed with fewer particles per line, letter and image. The yield that manufacturers provide for their toner cartridges are almost always based on a 5% coverage which does mean that your results will vary. Even so, the high yield cartridges are a great buy.
